RePer-AGE: Reorganization of Visuo-cognitive Functions Based on Peripheral Vision With Aging

The RePer-AGE study investigates how central and peripheral vision contribute to visual recognition and how these mechanisms change with normal aging. The study is based on the hypothesis that peripheral vision provides rapid global information that supports visual recognition through predictive mechanisms. Healthy young adults (18-30 years) and older adults (60-85 years) will undergo visual psychophysical testing, ophthalmological examinations, and, for a subset of participants, functional magnetic resonance imaging (fMRI). The results are expected to improve our understanding of age-related changes in visuo-cognitive functions and provide reference data for future studies on age-related visual disorders.
